This invention relatesto certain'new and useful improvementsin oint chairs and rail locks.

' Referring more in detail'to the accompanyin'g drawings, the reference numerals 1O designate the meeting ends of rails, each 35 of whichhas a slotted opening 11 in the web portion thereof as shown in Figure 6, each rail 7 end asshown in Figure 8 also having an open; ing 12therein inwardly of the slotted opening ll'for purposes presently to appear. j The meeting rail ends are adaptedfor seating in a'joint chair comprising a base plate13 upon which'the rail endsare seated and a pair of hinged side walls 14 and 15 hinged to opposite sidefedges thereof as at 16, the side walls 14: and 15 performing'the functions of fish plates or splice bars. A pin 17 projects laterally from the side face of the side Wall 141 atla point adjacent each end thereof for passage through the openings 12 in the rail the sidewall 15; being notched as at 18 pro vidingplearances forthe pins 17 when the I side walls '14 and 15 are in assembled relation relative; to themeeting rail ends as shown in vFigures,7f'and 8ii Each pin 17 projectsou'twaridly of the side wall 15 and in its project 7 ing end is provided-with atransverse open ing 19, a retaining rod 20 being'positioned in saidopenings outwardly of the'side' wall15 rod "20 passing beneath overhanging flanges 15a at each-end of the side wall 15 as illustrated to aid in'retaining the rod in position.

Ap irof staplesorlock bolt keepers 21 project laterally from the inner faces of the sidewall 14 of tlie joint chair adjacent the pins17 and extend 'throughthe slotted openingsll in the meetingrail ends to project into a pocket or compartment 22 formed on the 99 innerfa'ce of the side wall l5 intermediate its The lock-mechanism for, retaining the rail ends in assembled relation in the joint chair is SBii'llltO the compartment 22 and comprises an open sided'casing having one side wall 23, end walls 24, a bottom wall 25 and a top wall 26, the closed sidewall 23 of the lock cas- .ingbeing'plaeed in engagement with the webs of the meeting railends and having openings 27 therein'registering with the openings 11 in the rail Webs, the bolt keepers 21 extending through the registering openings 11 and 27 as shown in Figs. 3 and 5.

The lock mechanism comprises a vertically slidable tensioned plate 28 having pairs of lugs 29 and 30 projecting from the upper and lower edges thereof that are slidably mounted upon guide pins extending between the bottom and top walls 25 and 26 of the lock casing, the lower ends 31 of the guide pins being of increased diameter relative to the upper ends 32, while a coil spring 33 surrounds each guide pin between the lug 29v and the upper end of the lower enlargement 31 for tensioning the plate 28 in an upward direction. Each end of the sliding plate 28 carries a lock bolt '34 to be engaged by the adjacent keeper 21. by the plate 28 supports a perpendicular pin 36 which carries at its upper end a hollow push button 37 moving into guideways 38 formed in the side portions of the treads of the rail ends as illustrated. A lever for controlling operation of the sliding plate 28 and shown at 39 is pivotally mounted as at 40 upon the plate 28 with a finger 41 upon its lower end adapted to be moved into alignment with the opening 42 in the bottom wall 25 of the lock case, the upper end of the lever 39 being bifurcated as at 43 so that an implement 01 key inserted through the opening 44 in the hollow push button 37 is positioned between the furcations 43 of the lever for moving the same upon its pivot 40 to. displace finger 41 laterally of the opening 42 for engagement with the bot-tom wall 25 of the lock case as shown in Figure 3 to hold the sliding plate 28 against movement. The lever 39 is re tained in its adjusted position against movement b the leaf spring 45 guided at its ends upon the pins 31 and engaged intermediate its ends by the lug 46 upon the finger 41.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once he apparent, it being noted that the rail ends are moved laterally into position on the bottom wall 13 of the joint chair with the pins 17 and keepers 21 carried by the side wall 14 of the chair movable through the openings 11 and 12 in the rail ends. The lock mechanism is then disposed in engagement with the sides of the rail webs by first depressing the plunger button 37 so that upon release thereof the bolts 34 move into engagement with the keepers 21.

The lever 39 is then moved upon its pivot 40 to hold the sliding plate and lock bolts against movement. Upon closing the side wall 15 of the joint chair, the pins 17 passthrough the cut away portions 18 and the locking rod 20 1s inserted through the openings 19. in the projecting ends of the pins 17. a

While there are herein shown and described the preferred embodiments of the invention,

A center lug 35 carried it is nevertheless to be understood that minor changes may be made therein without departing from the spirit of the invention or the scope of the sub-joined claims.
